Class AstPivotNode

The Pivot transformation creates a less normalized representation of a data set by taking multiple rows and converting them into a single with multiple columns.

Constructors

AstPivotNode(IFrameworkItem)

Initializes a new instance of the AstPivotNode class with the specified parent node.

Properties

ErrorPath

Gets the error output path for this transformation

FriendlyTypeName

Gets the friendly name of the type of this node

FriendlyTypeNameStatic

Gets the friendly name of the type of this node

Inputs

This is a collection of mapping definitions that specify configuration information for each of the columns that will serve as inputs to the pivot process.

OutputPath

Gets the output path for this transformation. This is the preferred output path and will automatically connect to any single-input transformation nodes that directly follow it in the Biml file.

Outputs

This is a collection of mapping definitions that specify configuration information for each of the columns that will serve as outputs from the pivot process.

PassThroughUnmatchedPivotKeys

Causes the Pivot Transform to ignore rows containing unrecognized values in the Pivot Key column and to report the complete list of unmatched values at the end of DataFlow execution. Useful for collecting a list of values from input rows that can be used to automatically generate output columns.

PassThroughUnmatchedPivotKeysDefaultValue

Gets the default value for the PassThroughUnmatchedPivotKeys property

Methods

BindingScopeBoundaries()

Retrieves the permitted scope boundaries to bind references from this node.

CopyFrom(IFrameworkItem, UnboundReferences)

Instructs the node to copy property values from the supplied node into itself. This method should only be used by the internal Biml framework.

DefinedAstNodes()

Retrieves a collection of nodes that have been defined as direct children of the current node.

Duplicate()

Creates a duplicate of the current node

Duplicate(Dictionary<IFrameworkItem, IFrameworkItem>)

Creates a duplicate of the current node with the scoped node mapping

Duplicate(IFrameworkItem)

Creates a duplicate of the current node with the specified parent item

Duplicate(IFrameworkItem, Dictionary<IFrameworkItem, IFrameworkItem>)

Creates a duplicate of the current node with the specified parent item and scoped node mapping

DuplicateHusk(IFrameworkItem)

Creates an empty object into which the values from the current node will be duplicated. This method should only be used by the internal Biml framework

DuplicateInto(IFrameworkItem, Dictionary<IFrameworkItem, IFrameworkItem>)

Copies the values from the current node into a husk object with the specified scoped node mapping. This method should only be used by the internal Biml framework

EmitXmlForAction(AstEnginePropertyAction)

Instructs the node to make changes to its underlying Biml code that correspond to the provided action. This method should only be used by the internal Biml framework.

EmitXmlForProperty(String, Int32)

Instructs the node to make changes to its underlying Biml code that correspond to the provided property and index. This method should only be used by the internal Biml framework.

GetAllItemsReferencedByDefinedSuccessors()

Builds a list of all items referenced by this node and its successors. Each tuple in the returned list represents a FrameworkItemReference. The first item is the ReferencingItem, the second item is the property name, and the third item is the ReferencedItem.

GetBimlAttributeFragment(CulturedStringBuilder)
GetBimlChildFragment(CulturedStringBuilder, Int32)
GetBimlFragment(CulturedStringBuilder, Int32, Boolean)

Internal method used by the Biml engine to produce the XML code for the current object.

GetDefaultValue(String)

Retrieves the default value for the property with the name propertyName

GetDefaultValue<T>(String)

Retrieves the default value for the property with the name propertyName

GetJson(StringBuilder, ref Boolean, Boolean, Boolean, Boolean, Boolean, Boolean, Boolean, Boolean)

Generates a JavaScript Object Notation (JSON) representation of the current node

GetPotentialParentProperties()

Retrieves the reflection information for related properties of this node type.

GetPropertyValue(String)

Retrieves the current value for the property with the name propertyName

GetReflectionInfoFromXmlParsePath(String)

Retrieves the reflection information corresponding to the Xml parse path beginning at this node.

HasAnyBimlChildNodes()
MergeFrom(IFrameworkItem, UnboundReferences, Boolean)

Instructs the node to merge property values from the supplied node into itself. This method should only be used by the internal Biml framework.

NotifyCollectionPropertyChanged(Object, String, NotifyCollectionChangedEventArgs)

Internal Biml framework method used to notify this node that the specified collection property value has changed.

ParseAttribute(XAttribute, ParserContext)
ParseChild(XElement, ParserContext)
StructureEquals(Object)

Compares this node to the provided object to determine if all defined children and references are equal.
